As shown in FIG. 2, an embodiment of the present disclosure provides a resource configuration method, including:

Step S110: Configure the same physical uplink control channel (PUCCH, Physical Uplink Control CHannel) resource set for the sub-slots included in a time slot, where the PUCCH resource set includes: one or more PUCCH resources;

Here, each time slot can be divided into a plurality of equal or unequal sub-time slots. For example, in order to realize the uplink feedback on the physical downlink shared channel (PDSCH, Physical Downlink Shared Channel) sent in the downlink as soon as possible, an uplink time slot (slot) is divided into a plurality of equal uplink subslots (subslots). In this way, each uplink sub-slot can have a hybrid automatic repeat request acknowledgement (HARQ-ACK, Hybrid Automatic Repeat request acknowledgement) feedback opportunity. Compared with the implementation in which only one HARQ-ACK feedback opportunity exists in one uplink time slot, this implementation manner can significantly reduce the HARQ-ACK feedback delay because the HARQ-ACK feedback can be performed in advance.

Here, the PUCCH resource (PUCCH resource) may be a collection of configuration parameters for configuring the PUCCH resource. Here, the time domain symbols occupied by different PUCCH resources can be different, which makes the time domain symbols corresponding to the PUCCH resources more diverse, and the terminal UE can flexibly select PUCCH resources with different time domain symbols, for example, based on different time domain symbols. PUCCH resources send HARQ-ACK messages. Here, it may be that the base station sends the configuration information of setting the same PUCCH resource set to the sub-slots included in one time slot to the terminal through RRC signaling at the RRC layer.

Here, the same physical uplink control channel PUCCH resource set is configured for the sub-slots contained in a time slot. There is no need to configure a respective PUCCH resource set for each sub-slot, so when the configuration information of the PUCCH resource set is issued , There is no need to issue the configuration information of the PUCCH resource set for each sub-slot, thereby reducing the overhead of issuing configuration information.

Step S120: When the time domain symbol occupied by the first PUCCH resource in the PUCCH resource set exceeds the boundary of the time slot, the first PUCCH resource is discarded.

The start position and end position corresponding to the time domain symbols occupied by each PUCCH resource are required to be contained in one time slot. In an embodiment, multiple sub-slots contained in a time slot are independently configured with PUCCH resource sets, that is, each sub-slot in a time slot is configured with a set of time domain symbol lengths that match the time domain symbol length of the time slot. PUCCH resource set, which can ensure the flexibility of PUCCH resource configuration. However, independently configuring the PUCCH resource set for each sub-slot needs to issue a lot of configuration information, which will increase the overhead of issuing configuration information.

In another embodiment, only one set of PUCCH resource sets are configured for sub-slots, and this set of PUCCH resource sets is applied to each sub-slot. However, in order to ensure that the time domain symbols occupied by the PUCCH resources in this set of PUCCH resource sets do not exceed the boundary of the time slot, the time domain symbols occupied by all PUCCH resources in this set of PUCCH resource set configuration must be included in a sub-slot It cannot exceed the boundary of the sub-slot. For example, in the sub-slot division mode in which each sub-slot occupies 2 time-domain symbols, the time-domain symbols occupied by the configured PUCCH resources are configured to at most 2, because the time-domain symbols occupied by the configured PUCCH resources are limited This method will limit the flexibility of PUCCH resource configuration, and will directly cause the UE to be unable to flexibly select PUCCH resources with more time-domain symbols. For example, the UE cannot send HARQ-ACK messages through PUCCH resources with more time domain symbols. In the embodiment of the present disclosure, when the time domain symbol occupied by the first PUCCH resource in the PUCCH resource set exceeds the boundary of the time slot, the entire first PUCCH resource is discarded. In this way, the PUCCH resource occupying more time domain symbols can be configured to reduce When the uplink power is limited or the uplink quality is poor, the UE can only use the PUCCH that occupies fewer time-domain symbols, which will affect the coverage of the PUCCH channel that occupies fewer time-domain symbols. Here, discarding the entire PUCCH resource or discarding a part of the PUCCH resource means that all or part of the physical resources mapped by the PUCCH resource configuration are no longer used for data or information transmission.

In the embodiments of this application, on the one hand, the same physical uplink control channel PUCCH resource set is configured for the sub-slots contained in a time slot. In this way, there is no need to configure a respective PUCCH resource set for each sub-slot. When the configuration information of the PUCCH resource set is issued, there is no need to issue the configuration information of the PUCCH resource set for each sub-slot, thereby reducing the overhead of issuing configuration information. On the other hand, when the time domain symbol occupied by the first PUCCH resource in the PUCCH resource set exceeds the boundary of the time slot, the first PUCCH resource is discarded. In this way, the PUCCH resource that occupies more time domain symbols can be configured and the uplink power is reduced. When limited, or when the uplink quality is poor, the UE can only use the PUCCH that occupies fewer time-domain symbols, which will affect the coverage of the PUCCH channel that occupies fewer time-domain symbols. The embodiments of the present application can improve the uplink coverage of the PUCCH and improve the flexibility of PUCCH resource configuration in the time domain.

Here, the multiple PUCCH resources include: multiple PUCCH resources occupying different time domain symbols. Here, PUCCH resources of different time domain symbols may have different starting positions. Please refer to Figure 3 or Figure 4 again. The PUCCH resources include four different PUCCH resources numbered 1, 2, 3, and 4. The time domain symbols occupied by the PUCCH resources numbered 1, 2, 3, and 4 correspond to 10, 2, 2, 4, the PUCCH resource configuration of different time domain symbols makes the UE more flexible in selecting PUCCH resources. For example, the UE can flexibly select PUCCH resources with more time domain symbols to send HARQ-ACK messages. In an embodiment, a plurality of PUCCH resource sets including multiple PUCCH resources occupying different time domain symbols are generated according to the number of bits required to transmit the uplink control information UCI; the sub-slots contained in a slot are configured with the same The physical uplink control channel PUCCH resource set includes: the same PUCCH resource set selected from multiple PUCCH resource sets for the sub-slots contained in one slot.

Here, discarding the first PUCCH resource includes discarding the entire first PUCCH resource or discarding a part of the first PUCCH resource.

As shown in FIG. 3, an embodiment of the present disclosure provides a schematic diagram of the entire PUCCH resource being discarded in a resource configuration method. Here, each time slot includes two subslots, namely subslot0 and subslot1. Among them, each sub-slot occupies the length of 7 time-domain symbols (referred to as "7 symbols" in simplified description in Figure 3), and the corresponding PUCCH resource set includes four different PUCCH resources numbered 1, 2, 3, and 4. , The time domain symbols occupied by each PUCCH resource correspond to 10, 2, 2, and 4 respectively. In subslot1, the time domain symbol (10 symbols) occupied by the PUCCH resource numbered 1 in the PUCCH resource set exceeds the boundary of the time slot, and the entire PUCCH resource configuration numbered 1 is discarded, that is, the PUCCH numbered 1 is no longer used All physical resources mapped by the resource configuration are used for data or information transmission (in Figure 3, "X" shows the discarded PUCCH resource numbered 1).

As shown in FIG. 4, an embodiment of the present disclosure provides a schematic diagram of a part of PUCCH resources being discarded in a resource configuration method. Each time slot includes two subslots, namely subslot0 and subslot1. Among them, each sub-slot occupies the length of 7 time-domain symbols (simplified as "7 symbols" in Figure 4), and the PUCCH resource set includes four different PUCCH resources numbered 1, 2, 3, and 4. The time domain symbols occupied by the PUCCH resources correspond to 10, 2, 2, and 4 respectively. In subslot1, the time domain symbol (10 symbols) occupied by the PUCCH resource numbered 1 in the PUCCH resource set exceeds the boundary of the time slot, and part of the configuration of the PUCCH resource numbered 1 is discarded, that is, the PUCCH numbered 1 is no longer used Part of the resource configuration mapping part of the physical resources for data or information transmission (the "X" in the figure shows the configuration of the partially discarded PUCCH resource number 1), which is equivalent to the time domain symbol occupied by the PUCCH resource is Truncated.

It can be known that, in the embodiment of the present application, discarding the first PUCCH resource includes discarding the entire first PUCCH resource or discarding a part of the first PUCCH resource. This can configure PUCCH resources that occupies more time-domain symbols, which reduces when the uplink power is limited or the uplink quality is poor, the UE can only use the PUCCH that occupies fewer time-domain symbols, which results in less time-domain occupation. The impact of the symbol's PUCCH channel coverage is limited. The embodiments of the present application can improve the uplink coverage of the PUCCH and improve the flexibility of PUCCH resource configuration in the time domain.

Here, when the time domain symbol occupied by a PUCCH resource exceeds the boundary of the time slot, part of the PUCCH resource is discarded, including: when the time domain symbol occupied by a PUCCH resource exceeds the boundary of the time slot, discarding the PUCCH resource beyond the time slot boundary The time domain symbol of the boundary.

Please refer to Figure 4 again, the time domain symbol occupied by the PUCCH resource numbered 1 is 10, which exceeds the boundary of the time slot. At this time, the time domain symbol whose PUCCH resource exceeds the boundary of the time slot can be discarded, which is equivalent to PUCCH resource The occupied time domain symbols are truncated from 10 to 7 (10 minus 3), which can ensure that the start and end positions corresponding to the time domain symbols occupied by the PUCCH resource are contained in one time slot.

As shown in FIG. 5, another embodiment of the present disclosure provides a resource configuration method. The method includes:

Step S510: Configure multiple sets of PUCCH resource sets for the sub-slots contained in a time slot; wherein, each set of PUCCH resource sets is applicable to one or more sub-slots contained in the time slot, and the PUCCH resource sets include: one or more PUCCH resources.

The PUCCH resource may be a collection of configuration parameters for configuring the PUCCH resource. Among them, the time domain symbols occupied by different PUCCH resources can be different, which makes the time domain symbols corresponding to the PUCCH resources more diverse, and the terminal UE can flexibly select PUCCH resources with different time domain symbols, for example, based on different time domain symbols. PUCCH resources send HARQ-ACK messages.

Here, multiple sets of PUCCH resource sets are configured, and each set of PUCCH resource sets is applicable to one or more sub-slots contained in a time slot. It can be configured to configure each set of PUCCH resource sets and specify that each set of PUCCH resource sets is applicable to Which sub-slots in the time slot. Take multiple sets of PUCCH resource sets including PUCCH resource set numbered 1 and PUCCH resource set numbered 2, and time slots include subslot0, subslot1, subslot2, and subslot3 as an example: you can specify the PUCCH resource set numbered 1 to apply to subslot1 , The PUCCH resource set numbered 2 is applicable to subslot0, subslot2, and subslot3. In the embodiments of the present disclosure, each PUCCH resource set is applicable to one or more sub-slots included in a time slot. Compared with each sub-slot that needs to be independently configured with a different PUCCH resource set, the resource set can be saved. At the same time, the configuration information overhead when configuring resource sets independently is reduced.

Here, configuring multiple sets of PUCCH resource sets for sub-slots included in one slot further includes: setting the same PUCCH resource set for sub-slots with the same number of time domain symbols included in one slot.

Here, in the way of unequal sub-slot division, a slot can contain sub-slots with different numbers of time-domain symbols, such as 3/4/3/4 subslot (that is, the length of the time-domain symbols of the sub-slots is 3 respectively). , 4, 3, 4) Division method. In the above division method, for two sub-slots occupying a length of 4 time domain symbols, it can be configured to share a PUCCH resource set (configuration A). For two sub-slots occupying a length of 3 time domain symbols, It can be configured to share a set of PUCCH resources (configuration B). In configuration A, a PUCCH resource set of 4 time domain symbols can be configured; in configuration B, a PUCCH resource set of 4 time domain symbols can be configured. Compared with configuring different PUCCH resource sets for each sub-slot independently, the number of PUCCH resource sets required is reduced, which can save resource sets and reduce the configuration information overhead when configuring resource sets.

Furthermore, the present disclosure also provides two specific embodiments to further understand the PUCCH resource configuration method provided by the embodiments of the present disclosure.

Example 1:

A specific embodiment of the present disclosure provides a resource configuration method, which includes:

Step S610: Configure the same physical uplink control channel resource set for the sub-slots included in one time slot.

Here, the PUCCH resource set includes: one or more PUCCH resources. Here, multiple sub-slots in a slot share a set of PUCCH resources, that is, different sub-slots have the same PUCCH resources.

Step S620: When the time domain symbol occupied by the first PUCCH resource in the PUCCH resource set exceeds the boundary of the time slot, discard the entire first PUCCH resource or discard a part of the first PUCCH resource.

Here, although the PUCCH resources are the same, for a particular sub-slot, if the length of the time domain symbol occupied by a certain PUCCH resource exceeds the slot boundary, the PUCCH resource will be discarded. It can include the following two ways:

Method 1: Please refer to Figure 3 again. For a specific sub-slot, if the length of the time domain symbol occupied by a PUCCH resource in the PUCCH resource set exceeds the slot boundary, the PUCCH resource will be discarded entirely .

Method 2: Please refer to Figure 4 again. For a specific sub-slot, if the length of the time domain symbol occupied by a PUCCH resource in the PUCCH resource set exceeds the slot boundary, then the part of the PUCCH resource that exceeds the boundary Will be discarded, which is equivalent to the PUCCH resource being truncated.

In this specific embodiment, on the one hand, the same physical uplink control channel PUCCH resource set is configured for the sub-slots contained in a time slot. In this way, there is no need to configure its own PUCCH resource set for each sub-slot. When the configuration information of the PUCCH resource set is issued, there is no need to issue the configuration information of the PUCCH resource set for each sub-slot, thereby reducing the overhead of issuing configuration information. On the other hand, when the time domain symbols occupied by the PUCCH resources in the PUCCH resource set exceed the boundary of the time slot, the entire PUCCH resource or part of the PUCCH resource is discarded, instead of when the time domain symbols occupied by the PUCCCH resource exceeds one sub-slot The PUCCH resource configuration is discarded when the boundary is at the boundary of the network. In this way, the PUCCH resource that occupies more time domain symbols can be configured, which reduces the time when the uplink power is limited or the uplink quality is poor. The PUCCH of the domain symbol brings about the limited coverage of the PUCCH channel that occupies less time domain symbols. The embodiments of the present disclosure can improve the uplink coverage of the PUCCH and improve the flexibility of PUCCH resource configuration in the time domain.

In some embodiments, the maximum code rate of the PUCCH resource is configured in the PUCCH configuration information (Configuration) in the RRC layer, and the code rate on the PUCCH resource does not exceed this code rate. In the configuration of the PUCCH resource set, the maximum number of uplink control information (UCI, Uplink Control Information) bits that can be carried in this resource set will be configured. Each PUCCH resource in the resource set can carry the maximum allowable number of UCI bits. In this way, when the base station determines the PUCCH resource set to be selected according to the number of UCI bits, it can be in the resource set according to specific requirements (such as processing delay, Orthogonal Frequency Division Multiplexing) or CP-OFDM, whether there is multiple user multiplexing and other factors) flexibly select any PUCCH resource in the resource set. Then, when the sub-slot is configured, if the PUCCH resource is truncated because the PUCCH resource exceeds the slot boundary, the truncated PUCCH resource may not be able to carry the maximum allowable UCI bit number of the original RRC configuration Case. That is to say, the number of UCI bits that can be carried by the truncated PUCCH resource under the condition that the maximum code rate is satisfied is less than the maximum allowable number of UCI bits configured in the PUCCH resource set to which it belongs. Then, the base station needs to calculate the number of UCI bits that can be carried by the truncated PUCCH resource when selecting a specific PUCCH resource. Therefore, method 1 is a more suitable method. In mode 1, the existing PUCCH resource selection and determination process can still be used.

Example 2:

Another specific embodiment of the present disclosure provides a resource configuration method, which includes:

Step S710: Configure multiple sets of PUCCH resource sets for the sub-slots included in a time slot; wherein, each PUCCH resource set is applicable to one or more sub-slots included in the time slot, and the PUCCH resource set includes: one or more PUCCH resources.

Here, multiple sets of PUCCH resource sets are configured, and for each set of PUCCH resource sets, it is specified which sub-slots in the time slot are applicable to. In this specific embodiment, the time domain symbol lengths included in the divided 4 sub-slots are 3, 4, 3, and 4 respectively. For two 4-symbol sub-slots, a PUCCH resource set can be shared, corresponding to configuration A ; For two 3-symbol sub-slots, a PUCCH resource set can be shared, corresponding to configuration B. In configuration A, PUCCH resources occupying 4 time domain symbols can be configured; in configuration B, PUCCH resources occupying 4 time domain symbols can be configured.

In this specific embodiment, each set of PUCCH resource sets is applicable to multiple sub-slots included in one slot, which can save resource sets compared with different PUCCH resource sets that need to be independently configured for each sub-slot. At the same time, the configuration information overhead when configuring resource sets independently is reduced.

As shown in FIG. 6, a schematic structural diagram of a PUCCH resource configuration device provided by an embodiment of the present disclosure. An embodiment of the present disclosure provides a connection configuration device, and the device includes:

The first configuration module 61 configures the same physical uplink control channel PUCCH resource set for the sub-slots included in one time slot, where the PUCCH resource set includes: one or more PUCCH resources;

The processing module 62 is configured to discard the entire first PUCCH resource when the time domain symbol occupied by the first PUCCH resource in the PUCCH resource set exceeds the boundary of the time slot.

Here, the first configuration module 61 is further configured that the multiple PUCCH resources include multiple PUCCH resources occupying different time domain symbols.
